Nicholas Piggin d83f4bc0a4 powerpc/perf: Fix disabling BHRB and instruction sampling 
commit ea142e590aec55ba40c5affb4d49e68c713c63dc upstream.

When the PMU is disabled, MMCRA is not updated to disable BHRB and
instruction sampling. This can lead to those features remaining enabled,
which can slow down a real or emulated CPU.

Fixes: 1cade527f6 ("powerpc/perf: BHRB control to disable BHRB logic when not used")
